A finder is a type of weave made with the One Power.
A channeler uses Spirit and places the finder on an object. Somewhat akin to the Warder bond, but "much less complex", it allows the channeler to sense the direction and distance to the object. A finder will last for weeks on cloth and leather and will last indefinitely on metal. If the person holding an object that has a finder on it loses the object, the channeler can no longer find the object. Furthermore, the finder is attuned only to the one who wove the weave.
